4.11 Operating the CHIEMSEE EX explosion protected pump
4.11.1 Explosion protection
CHIEMSEE EX has the explosion designation II2G Ex db IIB T4 Gb. Broken down, this
designation means:
:
Symbol for explosion protected equipment
II: Equipment group II means that the equipment may only be used above ground.
2: Equipment category: Equipment category 2 enables the use of the pump in explosion
zones 1 and 2, but not in explosion zone 0.
G: Type of hazard, here G is for gas.
Ex: Designation for explosion protected equipment
d: Type of ignition protection, in this case for pressure-tight enclosure, i.e. if sparks or
explosions arise inside the motor, the pressure-tight enclosure prevents these from
penetrating to the outside.
b: Type of ignition protection with EPL
IIB: Explosion group, here IIB, through this, the pump is suitable for applications which
need the explosion group I, IIB and IIA. However, the equipment must not be used
in applications which require the explosion group IIC.
T4: Temperature class: T4 means that the surface of the pump or pump parts never
reach a temperature of 130 C. In this way, the pump can be used in all areas where
the ignition temperature of ambient gas or liquid is above 130 C, i.e. in the tempera-
ture categories T1 to T4.
Gb: Device protection level, device with high protection level for use in hazardous areas,
which in case of normal operation or foreseeable failures/malfunctions causes no
ignition hazard
Also see the following table:
(This table describes the operating limits and / or explosion approval). The chemical resistance of the pump to the sub-
stances listed here is not always given.)
4.11.2 Motor protection plug of CHIEMSEE EX
Caution:
All CHIEMSEE EX pumps are fitted with a motor protection plug which is different to a
standard motor protection plug (see image 4). However, the CHIEMSEE EX motor protec-
tion plug is not explosion protected. For this reason, the plug may only be operated on FI-
secured CEE sockets outside the explosion zone.
